This means: At what time do you wake up? Therefore this is your own answer BUT you can try to write: "Yo me despierto a las ____", this means: "I wake up at ___" so write the number of the hour you actually wake up at.
The only thing i would change is the word “ir” into the word “vaya.” it’s grammatically correct. besides that you did a fantastic job!
